Definitions

  • the present invention relates to a household appliance using a hydrophilic powder, comprising a metering chamber for this powder and means for transferring this powder to a container.
  • the invention relates more particularly to a household appliance for preparing hot or cold drinks based on soluble powder such as coffee, powdered milk chocolate, etc.
  • Apparatuses are known intended, not for household use, but for public use and which are generally stationary, which make it possible to prepare drinks, by means of the introduction of coins into these apparatuses. Such devices are described for example in French patents 2 323 361 and 2 365 995.
  • the powder is transferred from a powder reserve to a metering chamber thereof, by gravity.
  • the transfer of the powder from the metering chamber to a chamber for mixing this powder with water, milk or other liquid is carried out by gravity.
  • the vapor of the liquid which is formed during the heating thereof tends to rise towards the powder metering chamber and towards the powder reserve, which causes agglomeration thereof and seriously disrupts the operation of the device.
  • a device for public use using a hydrophilic powder such as coffee, cocoa, sugar, etc. comprising a metering chamber for this powder and means for transferring this powder to a mixing container according to which a momentary stream of air is formed having a flow and pressure sufficient to propel the powder from the metering chamber to the container in which this powder is mixed with a liquid such as hot water.
  • the steam of hot water risks entering the conduits for conveying the hydrophilic powder to the mixing container, agglomerating this powder and thus clogging the aforementioned conduits.
  • the object of the present invention is to create a household appliance using a hydrophilic powder which is compact and of simple construction, while avoiding any risk of agglomeration of the hydrophilic powder by the vapor formed in this appliance.
  • the household appliance using a hydrophilic powder comprising a metering chamber for this powder and means for transferring this powder to a mixing container in which this powder is mixed with a liquid
  • these means comprising means for forming a momentary air stream having a sufficient flow and pressure to propel the powder from the dosing chamber to the mixing container
  • it comprises a turbine driven by a motor to create a stream of air between the base of the metering chamber and an opening which opens into a channel connecting this metering chamber and the mixing container
  • the base of the metering chamber comprising means for preventing the passage of the powder while being permeable to the current of air and in that the aforementioned channel opens into the mixing chamber by a valve permeable to the air flow and to the powder coming from the metering chamber, but impermeable in the s ens inverse.
  • the air stream generated by the turbine blows the powder contained in the metering chamber towards the mixing chamber.
  • This current of air keeps the powder in the pulverulent state, avoiding any risk of agglomeration of the latter or of adhesion of this powder to the walls of the metering chamber and of the channel which connects the latter to the mixed. This risk is eliminated because the valve through which the channel opens into the mixing chamber prevents any penetration of liquid into this channel.
  • the apparatus according to the invention intended for preparing a hot drink, from a soluble powder such as coffee comprises a hopper 1 containing the soluble powder and closed by a cover 2, this hopper having at its lower part an opening 3 which opens into a cylindrical metering chamber 4 whose axis is vertical.
  • the lower part of the cylinder constituting the metering chamber 4 has a lateral opening 5 which communicates with a compartment 6 in which is mounted in rotation a turbine 7 whose vertical axis 8 is driven by an electric motor 9. This turbine 7 draws the outside air through duct 6a.
  • a piston 10 In the cylindrical metering chamber 4 is slidably mounted a piston 10, the head of which carries an annular seal 11.
  • This piston 10 has a lateral recess 12 which extends along practically its entire height, which allows the opening 5 to communicate with the interior of the piston 10 in all its positions inside the metering chamber 4.
  • the movement of the piston 10 is controlled by a lever 13 accessible to the user, which allows the latter to adjust the interior volume of the metering chamber 4.
  • the head of the piston 10 forms the base of the metering chamber 4, the position of which determines the volume of the powder which is introduced into this chamber.
  • the head of the piston 10 carries a valve 14, constituted by a disc of elastic material resting elastically on an opening formed in this head and fixed to the latter by a flexible articulation, which allows the valve 14 to be lifted under the effect of '' a pressure exerted inside the piston (see figure 2).
  • This valve 14 prevents the passage of the powder towards the interior of the piston 10, while allowing the passage of the air current which is blown by the turbine 7 inside the piston 10.
  • a lateral opening 15 which communicates with a substantially horizontal channel 16. This channel 16 opens into a mixing chamber which will be described later.
  • the opening 3 is closable by means of a sliding register 18 which can be actuated by the user.
  • the lower part of the hollow piston 10 is made airtight relative to the air inlet opening 5, by means of a disc 17 which follows the inner contour of the piston 10.
  • This disc 17 is fixed to the compartment 6 containing the turbine 7, under the air inlet opening 5.
  • the assembly shown in Figure 1 is mounted inside an outer housing 18a.
  • valve 21 (see FIG. 6) which is permeable to the current of air and to the powder propelled by the latter from the metering chamber 4. This valve 21 is however impermeable in the opposite direction.
  • the mixing chamber 20 comprises a blade 22 rotatably mounted on a vertical axis 23. This blade 22 is rotated by the motor 9 which drives the turbine 7 by means of a belt coupling 24 wound on pulleys 25, 26 .
  • the mixing chamber 20 comprises on its side wall, opposite the valve 21, small openings 27 for the evacuation of the air. Opposite these, two baffles 28, 29 are provided, shaped to prevent the powder and the liquid which are introduced into the chamber 20 from being driven out through these openings 27.
  • the bottom 30 of the mixing chamber 20 is conical and presents around the axis 23 of the blade 22 a series of holes 31 allowing the outlet of the prepared drink in the chamber 20. Under these holes 31 is placed a receptacle 32 for collecting the drink, which is placed on a base 33 which is part of the housing 18a. It can also be seen in FIG. 5, that the lower edge 22a of the rotary blade 22 is flush with the conical bottom 30 of the chamber 20. This blade 22, by rotating, creates a depression inside the chamber 20 which prevents the drink to flow through the holes 31.
  • a liquid reservoir 34 Above the mixing chamber 20 and next to the hopper 1 is placed a liquid reservoir 34, the bottom of which communicates with the interior of the chamber 20 by a valve 35. Near this bottom, there is a resistance heating 36.
  • the opening of the valve 35 is controlled by a bi-metallic element 37 or the like which is adjusted so that the valve 35 opens when the temperature of the liquid contained in the reservoir 34 reaches the desired value which is for example equal to 85-90 ° C in the case of coffee.
  • the register 18 which controls the opening and closing of the opening 3 is secured to a rod 38 which can be actuated manually by the user.
  • This rod 38 includes a stop 39 which can bear on the control button 40 of a temperature limiter 41, which has the effect of resetting the latter when the user puts the register 18 in the open position.
  • This temperature limiter 41 is placed in contact with the heating tank 34 (see FIG. 5).
  • the temperature limiter 41 comprises two electrical circuits A and B (see FIG. 7) reacting to different temperatures.
  • the movable armature 41a which is associated with the heating resistor 36 closes the circuit A, so that the resistor 36 is energized.
  • the movable frame 41b which is associated with the electric motor 9 is on the other hand in position opening, so that this motor is not supplied with current.
  • the movable armature 41 b of the electric circuit B goes into the closed position, thus controlling the power supply to motor 9.
  • the electrical resistance 36 continues to heat until the temperature of the liquid reaches a temperature equal, for example, to 95 ° C. At this moment, the movable armature 41a of the circuit A switches over and cuts off the electrical supply to the heating resistor 36 and to the motor 9.
  • the register 18 is opened and then closed, causing the limiter 41 to arm in its open position.
  • the resistor 36 begins to heat the water contained in the reservoir 34 and the coffee powder completely fills the metering chamber 4, that is to say the volume of the chamber 4 between the register 18 and the valve 14.
  • the motor 9 starts up causing on the one hand the rotation of the mixing blade '22 and creating on the other hand by rotation of the turbine 7 an air current which penetrates to the inside the piston and lifts the valve 14 of the latter.
  • This current of air drives the coffee powder contained in the metering chamber 4 towards the channel 16 and the mixing chamber 20 by pushing the valve 21 in passing.
  • the deformable blade 37 lifts the valve 35, which causes the passage of the hot water contained in the. reservoir 34 in the mixing chamber 20.
  • the motor 9 stops, as does the heating of the water.
  • the blade 22 being immobilized, the drink can then flow into the container 32.
  • the valve 21 closes as well. the valve 14. No water vapor can then rise to the hopper 1, to the metering chamber 4 and to the communication channel 16, so that any risk of water condensation likely to cause agglomeration of the powder is avoided.
  • the invention can be applied to any household appliance using a hydrophilic powder which must be transferred between a metering chamber and a container in which there is a risk of clogging by powder in the presence of condensed water or steam.
